QN NN tending portion 30. It will be noted that the side portions 26 and 27 are bent as at 31 and 32 so that the loop portion 29 andthe extending portion 30 may be positioned substantially in alignment with the end portion 21 of the rod 22.

The inclined portion 30 extends between the portions 26 and 27 and may be bent as at 33 for terminating in the gripping jaw portion 25. The end portion 34 of the jaw portion 25 extends beyond the arcuate-shaped portion 28 with which it is normally in engagement. A11 arcuate-shaped spring member 35 may be provided within the loop portion 29 of the rod member 22 and tends to positively and resiliently hold the end portion 34 of the clamping portion 25 in engagement with the arcuate-shaped portion 2B. The spring member 35 may be constructed of any suitable spring material such as vanadium .steel which may be subjected to high temperatures without losing its resiliency.

From the foregoing description of the various parts of the device, the operation thereof may be readily understood.

When the device is to be used such as for welding, the handle member l2 may bennscrewed from the body portion l and the electrical conducting wire or cable 37 connected with the body portion l by means of the clamping ineinber 4. The handie member i2 is then reconnected with the body portion. Another electrical conductor or cable, `not shown, may be connected with the material to ne welded for providing a circuit.

An electrode 35 of the size desired may then be positioned between the jan.T portions 2i. and 25 and is held by the gripping action oi the jaw portions. The jaw portion 25 may be provided with small recesses 38 therein whereby the electrode 36 may disposed in a dednite position with respect 'to the jaw members.

A switch is then actuated for permitting 'the current to iow through the cables and the device is ready forjuse.

When much or' the electrode been up in the welding process and it desired to substitute another electrode therefor, it is :nere-- ly necessary to use the new electrode for prying the jaw portions 24 and 25 slightly farther apart, thereby causing the Old electrode to be released by the jaw portions whereby it may fall therefrom. The new electrode is then slidably moved between the jaw portions. Thus it will be seen that the old electrode may be quickly and easily replaced by a new electrode without the operator having to handle a heated member. It will also be seen from the vabove description that the gripping member 22 may he quickly' and easily replaced by another gripping member if for any reason it may be found desirable to do so.

'We claim:

i. An electrode holder comprising a conducting body having an axial air passage thereln'ough, means for securing a conductor directly to the interior of said body, a member on said body bridging the forward open end of said passage, an electr-ode gripping member carried by said bridging member, and a hollow handle secured to the forward end of said body and inclosing the remainder of the same.

2. An electrode gripping member comprising a conducting rod having the rear end theri adapted to be engaged by a handle and comprising two integral jaws, one of said jaws comprising a forwardly extending portion and an integral rearwardly extending co-planar portion spaced from said first portion, said second jaw comprising the forward portion o said rod and being connected at its rear end to said second portion ofl said first jaw by an integral loop disposed in a plane normal to the plane of and between said first iaw portions, said cond jaw extending from said loop forwardly between said 'drst jaw portions at an angle intersecting the piane thereof and having its freeend disposed n electrode gripping reiation with respect to the forward end of said ilrst jaw, and a spring positioned Within said loop and acting on said second jaw in a direction to 4'increase the tension of said .iowa on an intermsed electrode.
